ADJUSTABLE HOSE CLAMP FOR MILKING MACHINES.

Application filed February 24,1927. Serial No. 170,605.

machine to control the capacity of each tube.

A second object of my invention is to proride a clamp which is strong and durable,

etlicient in its operation, has few moving parts, which is not likely to get out of order, and which is well adapted to perform the services required of it. Y

My invention however, is of universal ap' plication and can be used for example, on the rubber tube of a water-bag. It can also be used on water-hoses of various sizes, and for various other purposes either to shut off the water completely or lessen the pressure within the tube without necessitating the turning of the faucet handle or valve. The device can also be used as a clothes pin on blankets, quilts, carpets or the like, as well as for domestic purposes such as for lifting hot pie-plates, stove-lids or the like.

My device however, was primarily designed for dairy use. hen cows first freshen, the quantity of milk given from each quarter is practically the same, but for various reasons this quantity does not always remain the same. My adjustable hoseclamp is to be used for lessening the pressure and suction of air on the light quarters. Then, when the cups are taken oil the cow, each quarter will be dry or nearly so, as these quarters will have been milked proportionately.

With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claim, ref erence is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a plan View of my adjustable clamp showing the same applied to a pair of tubes.

Figure 2 is a sectional view taken along the lines 22 of Figure 1.

Figure 3 is a side elevation partly in. vertical section showing my adjustable clamp in such position on a pair of tubes that they are restricted to control the flow of fluid therethrough, and

Figure 4 is a view of a slightly modified and preferred form of my invention.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, my improved hose-clamp comprises a section of sheet macrial bent upon itself as at 2, to form a pziir of substantially parallel arms 3 and At the point of bending, the material is sprang outwardly slightly as at 5, so that the arms are urged apart by the natural resiliency of the metal of which the clamp is formed. The outer ends of the arms 3 and i are formed in a serpentine fashion, there being a pair of troughs 6 and 7,. 6 and 7" and a crest 8 and 8 011 each arm respectively. The outer ends of the arms are in" clined outwardly so as to extend away from each other as shown at 10 and 11. A suit-- able collar 12 is mounted on the arms 3 and c for sliding movement. 8

In the modification shown in Figure at, the troughs 6 and 7 have been brought nearer to each other whilethe troughs 6 and 7 have remained the same so that the pair of tubes shown at T and T respectively when held in position and clamped by my adjustable clamp, will be separated so thattheir adjacent sides will not interfere with each other.

My device is used as follows. The tubes T and T are placed in the depressions G and 7 between the outer ends of the arms 3 and at. An adjustment ofthe collar 12 then will serve to bring the outer ends of the arms together so that the trough 6 extends into the troughG, and the trough 7 extends into the trough 7 thus clamping firmly the tubes as clearly shown in Figure 3, and re-.

or scope of the invention as defined by the appended claim.

I claim:

A clamp adapted to hold a plurality-of flexible tubes and deform the same, said clamp comprising a flat sheet of material bent upon itself to form substantially parallel arms normally tending to be repelled,

understood that variousthe outer ends of said arms being in the sprung portion on said member adjacent its form of :1 serpentine and providing troughs hend adapted to prevent said collar from heund crests, the troughs of one of said arms ingr removed.

being closer together than the troughs of In testimony whereof I have signed my the other of said arms, and a collar sliduhle name to this specification.
